ELECTRICAL SGRUBBING AND DRYING: MACHINE.

Application filed August 20, 1924. Serial No. 733,167.

This invention relates to improvements in scrubbing machines and has for an object the provisionof a simple and durable mo.- tor operated scrubbing machine which may i be readily and conveniently manipulated and which will thoroughly and effectually cleanse the surface over which it is operated.

Another object of the invention is the provision of a machine of the above character which includes removable fresh and waste water. tanks or receptacles which form a part of thefmachine housing, so that when the said receptacles are removed access may be conveniently had to the interior of the machine. c

Another object of the invention is the provision of novel means for collecting Waste water from the brushes and conveying the said water to the waste water tank.

With the above and other objects in view, the invention further includes the following novel features and details of construction,

I to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim. In the drawings 2 Figure 1 is a side elevation of a scrubbing machine constructed in accordance with the invention. a a

Figure 2 is a top plan view ofthe same. Figure 3 is a central vertical sectional view. i or v Figure 4 is a section on the line 4-4 of Figure 3. V a

Figure 5 is a detail section'on the line 55 of Figure 1. p v

Figure 6 "is an enlarged fragmentary sec tion on the line 6-6 of Figure 5.

Figure 7 is asimilar view on theline 77 40 of Figure 1. v

Figure 8 is a fragmentary perspective view of a portion of the handle of the machine and showing theoperating levers carried thereby Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates the machine housing which ineludes side Walls and end walls. The front end of thishousing is supported upon roll- 11s or casters 11, while therear end is supported upon wheels 12. i

Mounted transversely at oppositeends of the housing 10 upon axles 13 are brushes ii and 15, the former being termed thescouring brush in that it receivessthe water or other cleansing agent and acts {to loosen the dirt, while the brush 15 is termed the gathering brush in that it gathers up surplus water from the scrubbed or scoured surface.

The brushes are motor driven and for this purpose there is provided an-electric motor 16 which is mounted within a motor compartment 17 and to which current may be supplied by a conductor wire or cord 18. The latter may have included therein a suitable controlling switch 19; Mounted upon the axles 13 and rigid with the brushes 14c and 15are beveled gears 19which are engaged by beveled pinions 20 secured to 0pposite ends of a shaft 21 which extends along one side ofthe housing 10 and which is rotatablein suitable "bearings. ,The gear 19 of the brushv 15 isdriven by a pinion 22 which is secured to one end of a shaft28 and this shaft is in turn driven by a gear connection 24: with the shaft of themotor 16. The brushes 14 and 15 will thus be rotated in opposite directions or in the direction indicated by the arrows in Figure 3. I

The side walls of the housing 10 are pro-t vided with upwardly extending inverted substantially V -shaped projections 25 while mounted upon the housing and engaging'the opposite inclined edges of the side walls 25 are tanks 26 and '27. The bottomsof these tanks form the top wall of thehousing and the space between the inclined bottom walls 28 0f the tanks provides a water collecting chamber 29 whose opposite ends are open to the brushes 14 and 15. Thechamber '29 is provided with a bottom wall 30.

The tank 26 provides a fresh water tank having a transversely extending channel or gutter 31 extending along the bottom thereof; This channel orgutteris in communication with the tank 26 by means of a port 32 which is controlled by a spring seated v'alve 33. The channel or gutter is provided with spaced openings 34 so that water entering this channel or gutter will be distrib uted transversely of the machine upon the lit ' to the' maehine housing.

forward portion of the brush 14. The tanks 26 and27 are provided with openings which are normally closed by caps 36.

The valve 33 has extending therefrom a stem 37 whose upper end is connected to one arm oi. a bell crank lever 38. This lever is pivotally mounted upon, the tank 36 as shown at 39 and has connected'to its other arm one end of a cable 40.- This cable can.

tends rearwardly over the top of the machine around a pulley 41, the said pulley being mounted upon a handle 42 which is secured The opposite end of the? cable is connected to an arm 43 which is pivotally mounted upon the handle 42 as! shown at 44; This armhas secured theretoaan operating handle 145 which engagesa toothed-segment 46 carried by thehandleQ so thatthe valve 33 may be opened and held in'open position.v H

:Located beneaththe.watercollecting chamber '29 and extending transversely, beneath thebottomQO of thesaidchamber is a receiving chamber 47Q-This chamber isprovidedwith an inclined bottom wall so as to direct water received therein to oneside of the chamber. Waterenters thechamber .47 from the collecting chamber through openings 48. which arclocated. in a depressed portion of the bottom 30 of the water collecting chamber. Thewater collecting chamber is royidedwith a vertically disposed centra ly arranged splash partition 49,;so that the openings water thrown upward intotheichamber 29 from the brushes 14. and 15. will strike this wall and pass portion of the bottom wallBO and through 48 into the receivingchamber 47.- Located within. the receiving chamber 47 is a pump 50 whiehis provided with openings 51 for the passageof waterfrom thecharnbcr 4.7 into the pump cylinder. ,The

piston of the pump 5(lhas connected thereto shaft 21. and

previously mentioned. Communicating with a rod or pitman 52 whichis eccentrically connectcd to'a gear 53. This gear is'driven by a pinion 54: which is mounted upon the driven from the motor 16 as one end of the pump 50 is a pipeor conduit 5 5 which extends upward through the water collecting chamber 29 and has its opposite end extending into the waste water chamber 27. Thus, waste waterfrom i the collecting chamber will pass, into the be conveniently removed;

receiving eha her and from this last mentionedchamber will be torced upwardunto as waste water tank through which it may The tanks 26, and 27 are provided with spaced deflecting walls 56, y Y Pivotally mounted at'the rear of thehousdownward to the! depressed of the housing,

111g 10 as shown at 57 is a wiper element 58. This element includes a rubber or other flexiblc engaging strip 59 which is yieldingly pressed into engagement with the scrubbed surface by means of springs 60. The element. 57 has connected thereto one end of a cable 61 which passes over a roller 62 and which is secured to an arm .63. This arm is pivotallylmounted as shown tit-64 upon, the hantile 42 and carries an operating handle 65 which engages atoothcd segment 66. By

this means the wiper element may be held in elevated position when desired. The tanks 26 and 27 are removably sccured upon the housing 10 and for this purpose their lower edges engage flanges 67 which extend around the housing. The

tanks have secured theretoistaples orloops 681=which removably receive hooks 69 "pivotally secured to thehousing.

The housing 7 is; provided at one an opening to-which access may be hadto the gears 53 and5 This opening isnormally closed by a pivotally mounted disk or clos'ure70., i

sidegwith In order toelevato themachino for movcwhen moved to the movement ot the arms .71 in one direction is limited by stops 72; while the rollers 70 may beheld in raised .or' inactivie 1 position by Springclips 73. i
